title: Lucky to meet RS3PE.
abstract: We present a florid case of remitting seronegative symmetrical synovitis with pitting edema that was actually a paraneoplastic syndrome of an asymptomatic undiagnosed adenosquamous lung cell carcinoma. The arthritis led to a screening for lung cancer and an early enough diagnosis for a curative intervention.
